Report produced by Population Strategy.

The CNA and Operational Capacity figures are taken from the latest signed cell certificates held by PS.

\*The prison unlock figure may be lower than the 'Population', as the 'Population' includes prisoners on authorised absence.

\*\*Useable Operational Capacity of the estate is the sum of all establishments’ operational capacity less 2000 places.

The report is compiled from data on the last working Friday in March 2015. Definitions of Accommodation Terms

Certified Normal Accommodation (CNA)

Certified Normal Accommodation (CNA), or uncrowded capacity, is the Prison Service’s own measure of accommodation. CNA represents the good, decent standard of accommodation that the Service aspires to provide all prisoners.

Baseline CNA

Baseline CNA is the sum total of all certified accommodation in an establishment except, normally: • Cells in punishment or segregation units. • Healthcare cells or rooms in training prisons and YOIs that are not routinely used to accommodate long stay patients.

In-Use CNA

In-use CNA is baseline CNA less those places not available for immediate use, for example: damaged cells, cells affected by building works.

Operational Capacity

The operational capacity of a prison is the total number of prisoners that an establishment can hold taking into account control, security and the proper operation of the planned regime. It is determined by the Deputy Director of Custody on the basis of operational judgement and experience.

Useable Operational Capacity

Useable Operational Capacity of the estate is the sum of all establishments’ operational capacity less 2000 places. This is known as the operating margin and reflects the constraints imposed by the need to provide separate accommodation for different classes of prisoner i.e. by sex, age, security category, conviction status, single cell risk assessment and also due to geographical distribution.

Establishments Exceeding their Operational Capacity

Governing governors and Controllers and Directors of contracted out prisons must ensure that the approved operational capacity is not normally exceeded other than on an exceptional basis to accommodate pressing operational need.
